Review on 🖨️ YOYI 3D Printing Filament: Advanced Additive Manufacturing Solutions by Ryan Nguyen

This filament is flexible but not elastic, which is strange because the filament itself is elastic but the printed objects are not. For example, if you printed a drinking straw in "vase mode", the result will behave like a real drinking straw - you can easily pinch it with your fingers or bend it in half, but like a plastic straw, you won't be able to stretch it. (By the way, don't use this to make straws; it's not food safe. But I digress :) I had a number of issues starting with this, including bloating ("pimples"), pulling, insufficient extrusion, and bad Layer sticking.. Here's how I solved them one by one: Fixed under-extrusion when I realized that the filament* itself is a little stretched and sometimes stretches and jumps during printhead movements without advancing the filament spool-- - leading to under-extrusion This was solved by fitting a spool holder with low-friction ball bearings, so even the slightest pull on the filament spins the spool rather than stretching the filament. I've overcome other pro problems in Simplify3D with the following settings (all other settings remain on default for a 0.40 mm nozzle, starting with PLA at medium quality): extruder tab: end tip, 0.20 mm; Wipe nozzle, 5mm (drop assisted) Temp: primary extruder, bed temp 1,250°C (this solved the layer adhesion problem) Cooling: fan speed layer 1 0 (actually no fan cools at all; again for adhesion) Advanced: perform retraction while moving . Avoid crossing yourself when moving. The last two settings helped with drips and tension respectively. I was kind of shocked that I had to crank the temp that high and forego cooling altogether, but until I did the vertical layers just didn't hold properly, especially when building something at a 45 degree angle. simply sag and fall past the previous layer. By getting it really hot, each new layer stuck to the last one. After these settings were dialed in, it printed perfectly on my direct drive Qidi X-Plus. Bowden tube printers usually have a harder time handling flexible filament, so remember that anti-backfeed helps a lot, and if you're still having trouble, try slowing down your print speed as well. (And check how your spool feeds!) If you like the principle of flexibility but not elasticity, and especially if you have a direct drive extruder, you should be very fine at dialing it in and getting great prints!
